Chapter 1 Overview of Safety Controllers
GuardPLC 2000 Controller, Power Supply, and I/O Modules
GuardPLC 2000 Power Supply
The 1755-PB720 power supply module provides two voltages
(3.3V DC and 5V DC) for the GuardPLC 2000 controller. They are
electrically isolated from the supply voltage, 24V DC.
1755-IB24XOB16 I/O Module
The 1755-IB24XOB16 digital input/output module provides 24 digital
inputs and 16 digital outputs. The status of each I/O signal is
displayed with a status indicator located on the right side of the front
plate connectors. Inputs and outputs are electrically isolated from the
supply voltage, 24V DC.
1755-IF8 Analog Input Module
The 1755-IF8 analog input module has eight inputs. These inputs can
be used as either eight single-ended inputs or four differential analog
inputs that are electrically isolated from the logic side of the GuardPLC
module. The measured input value can be either voltage or current. If
you use the input module for current, you need a shunt resistor. The
measured value is digitally transferred to the processor system as a
value between 0 and 2000.
